Abstract: A surface plasmon resonance (SPR) detector in which radiation from a laser source is reflected off a concave reflector to a point or line of incidence on the interface between a glass slide and a metal layer.  The single pencil beam from the laser is scanned by a moving mirror across a small arc, covering those angles of incidence within which surface plasmon resonance occurs. A sensitive, for example antibody, layer overlies the metal layer to form a combined layer, and a sample to be tested passed across the antibody layer.  Any binding which occurs with the antibody layer results in the refractive index of the layer changing, and this change may be detected by monitoring the strength of the beam internally reflected.  A light detector enables the beam to be measured.

Abstract: A method of and change to the lower portion of the slide gate to be asymmetrical  in the gate loading direction such that altering the supporting loading rail portions of the frame on  the  mechanism  to  prevent  loading  of  the  gate  in  the incorrect orientation is disclosed.  The frame for the existing sliding gate valve is asymmetrical about the gate change axis which  thereby  eliminates  the  requirement  or  left  and righthanded frames to make left and righthanded mechanisms.          The method to change a mechanism from a left to a righthand load requires two additional parts.   In this change the frame is changed to be asymmetrical and yet require only the same two additional parts to change from left to righthanded load.  Left and righthand load is defined by the operator's position being the firing cylinder end of the mechanism with the operator facing the mechanism.   A righthand  load mechanism has the loading port on the operators right side.   The lefthand load mechanism has the loading port on the left side.  The sliding gate valve frame is to be modified so that the gate loading rail on the cylinder end on the righthand side of the mechanism is  extended.    This  requires  a  righthand  load to  load the sliding gate with the long ledge towards the firing cylinder.          The same gate conformed by the method into a lefthand load valve assembly has the loading rail  away from the cylinder extended on the lefthand side of the mechanism.   This forces the gate to be loaded with the long ledge away from the firing cylinder during lefthanded loading.   Thereby, a single frame with the asymmetrical loading port arrangements, yet otherwise symmetrical along the firing axis,  enables a non-reversible sliding gate without the requirements of dedicated left and righthanded mechanism frame assemblies.   The slide gate has asymmetrical  loading  ledges  and  preferably  symmetrical throttling rails.

Abstract: DOWNRIGGER APPARATUS  FOR TROLLING               ABSTRACT OF THE DISCLOSURE           The apparatus spools a line carrying a weight for positioning a fishing lure at a desired depth in water for trolling.  The apparatus has a motor which rotates a spool carrying the line supporting the weight.  A brake automatically brakes the spool when the spool starts to unwind the line, which can occur when the motor is inoperative.  Braking force on the spool can be finely adjusted to permit slipping and controlled unwinding, so that the line does not break should the weight become fouled or hung up on the bottom.  Preferably, when winding up the weight, a clutch transmits torque between the motor and spool when the torque is below a slipping threshold torque.  However, the clutch slips when the slipping threshold torque is exceeded and simultaneously generates an audible warning  sound when slipping to protect the motor from overload if the weight becomes "hung up" when winding in.  An alternative electrical circuit breaker can be substituted for the clutch to protect the motor.

Abstract: The present invention relates to a system and a method of extraction liquid from a humid mass by compressing same. The system comprises a conduit of linear, circular or other shape through which the humid mass is displaced. The conduit is of rectangular cross-section, which cross-section can be constant or variable. Further, the conduit has perforated side walls along at least a liquid extraction working section of the conduit. The system further comprises elements which cause an axial pressure at the interior of the humid mass as well as a mechanism to displace at least one of the perforated side walls to convey the humid mass along the working section of the conduit in such a way as to generate between the interior surface of the perforated side walls and the humid mass a dynamic friction force which defines a pressure zone which is less than the axial pressure created by the pressure creating elements. This difference in pressure causes the liquid in the humid mass to flow out of the mass in a direction substantially transverse to the displacement direction of the humid mass and out through the perforated side walls of the conduit.

Abstract: An FM intermediate-frequency circuit into which there is integrated at least a limiter-amplifier (1A), a level detector included in the amplifier, and a phase-locked loop (2, 3, 4) which contains a VCO (4). A large dynamic range of the level detector is obtained without having to use excessive limiter-amplifier amplification, which would cause oscillation problems. In parallel with the said limiter-amplifier (1A) is at least a second limiter-amplifier (1B), in connection with which there is also a level detector. By means of a dividing circuit (R1, R2) the level of the input signal of the second limiter-amplifier (1B) is dropped. The signals (1A, 1B) obtained from the level detectors are combined to form one level detection signal (ITOT). If the signals are in the form of current, the combining can be carried out directly by summating the signals.
